Hey Dhanush,

Public Sector Undertaking (PSU) takes applicants through GATE scores and admission in IIT's and IISc M.Tech programs is also done through GATE. But the salary factor depends upon what you pursue after M.Tech, the type of placement you receive or any Government job you apply for. In case of PSU's some of the listed salaries are:

• Indian Oil Corporation (IOCL): 11,00,000/- CTC
• Bharat Petroleum Corporation Limited (BPCL): 10,50,000/- CTC
• Hindustan Petroleum Corporation Limited (HPCL): 9,50,000/- CTC

Note: These are an approximation and not the accurate data.

Whereas if we consider that one pursues M.Tech from one of the prestigious institution and gets placed on Campus Placement(CSE) then the salary record goes as:

• IIT Bombay: 18,50,000/- CTC average package
• IIT Delhi: ~15,00,000/- CTC average package

You see most of the students get placed in MNC's and private sectors which differ from PSU.

Also one could join a PSU after completing M.Tech as well, depends on what the student wish to so.
